H being rotated by known traversing bevel gears (not shown) as the feed carriage is reciprocated across the width of the horizontal feed lattice. The pivoted housing l for the carriage rollers is pressed downwards by a shaped plate spring 2| ing |5 supported by the studshaft I1 and the,

the sliver being fed be- 1 the driving pinion 20. When gins to wrap round or become entangled with 4 in said boss and loosely emshaft, is an upwardly inclined suitable fapei'ture bracing said stud lever arm 40 which projects from the belt fork feed rollers, the sliver trapped in the nip of said rollers forms a wedge which resists the rotation of said rollers by the driving pinion, with a resulting couple which overcomes the pressure of the plate spring 2|, and the carriage roller housing l5 pivots against the action of said spring,i

and gear wheel I8 is lifted out of mesh with the driving pinion 2D, and the drive to the rollers is interrupted. The housing I5 is held in tilted position by a catch, comprising a spring-controlled sliding member 23 movably mounted on the housing and having an inclinedface 24 formed thereon, and an adjustable stud 25 fixed in the cap 22 on the carriage frame It, the arrangement being such that when the housing is tilted, the spring 26 causes the sliding member 23 to move end-on, so makes contact with the lower extremity of the adjustable stud 25 and the housing I5 is held in tilted position. To rollers In, U have been cleared of the entangled sliver, a handle 2'1, pivoted at 28 on the cap 22 and connected to the sliding member 23 is operated to withdraw said member so that the inclined face 24 is moved clear of the adjustable stud 25, and the housing can then fall int0nor-- mal position under the action of the beforedescribed plate spring 2|.

Even though the drive to the carriage rollers W, H has been interrupted, it will be obvious that the carriage It will continue to be reciprocated across the carding engine, and mechanism is combined which is operated after the tilting of the carriage roller housing l5 has taken place.

Such mechanism comprises a shaped adjustable bar 29 having an extension 29a and being rigidly fixed by studs 30, 30 to the underside of the pivoted housing l5 the said bar working to a system of links mounted on the operative side of the framework of the carding engine. system of links consists of a substantially vertical handle or lever 3| pivoted at 32 to the carding engine frame 33 so as to be capable of angular movement. The vertical handle is so disposed as to be substantially in line with the extension 4 29a of the bar 29 mounted on the feed carriage, and said handle has an angle bracket 34 mounted thereon in such a position that the extension 29a normally passes beneath said angle bracket. About mid-way of the length of the handle is a fixed stud 35 which projects outwards at rightangles to said handle and longitudinally of the carding engine. bracket 35 attached to the carding engine frame 33 is a pivotally mounted belt fork 31, which controls the position of the driving belt with respect to the fast and loose pulley system on the main driving shaft of the Scotch feed, and said driv-;

ing belt is driven by a pulley mounted on the main shaft of the carding engine. The boss 38 of the belt fork is capable of angular movement about a stud shaft 39, and loosely fitting in. a

that the inclined face 24- re-set the housing after the" Such At the outer extremity of a boss inwards towards the carding engin frame. At the freeend of the inclined lever is fixed a downwardly'disposed catch 4| or rectangular extension disposed approximately at right angles to the inclined lever arm, and said catch has a shaped open gap or recess 4|.r formed therein 10 which embraces'thestud 35 mounted on the vertical handle 3|. Thus the inclined lever 40 is normally supported in position by the stud 35 on the vertical handle 3| lying in the recess 4|a: in

the catch 4|.

Two short links 42, 43, so disposed as to lie at an angle one to the other, are provided to support a pendent weight 44, and the upper extremity of the short link 42 is loosely mounted on a pivot 45 fixed to the inclined lever 40 and midway of its length, whilst the upper extremity of link 43 is pivoted on the stud 35 and disposed thereon between the handle 3| and the catch 4|. The lower extremities of the two short links 42, 43 are loosely mounted on a common stud 46 fixed in the top of the pendent weight 44.

Presuming the driving belt to be on the fast pulley 41 so that the Scotch feed system is driven,

then so long as the pivoted housing l5 for car-,

riage rollers I0, H is in normal position, the extension 29a of the: bar 29 will pass beneath the angle bracket 34 on the vertical handle 3|, and the rollers will feed the sliver to the lattice |2 whilst the carriage i6 is reciprocated in known manner to lay the sliver across the width of said lattice. When the silver begins to build-up on either of the rollers ID or H the housing I5 is tilted, in manner before described, and the bar 29 will be brought into' operative position, and the'fee'd carriage will continue to move across the width of the carding engine, until it reaches the operative side, whereupon the extension 290. will make contact with the angle bracket 34, and the vertical handle 3| will move about its pivot 32, and the stud 35 mounted on said handle will be forced out of the shaped recess 4|a: in the catch 4|, and the pendent weight will be free to fall by gravity andpull the lever 40 in a downward direction, so that said lever pivots about the belt fork stud shaft 39. This pivoting movement of the inclined lever 40 imparts angular.

motion to the belt fork 31, and the driving belt is shipped from the fast to the loose pulley 48, and the drive to the Scotch feed system is stopped. The downward movement of the lever 40 is limited by a stop 49 mounted on the belt fork bracket 36. The system of links above described are easily re-set and the beltyshipped from the loose to the fast pulley by moving the vertical handle in the opposite direction.

Mounted also on the carding engine framework, is a normally closed single-pole limit switch 50, which is connected to the electric motor (not shown) driving the carding engine, and such switch is normally held in closed position by the vertical handle 3|, the arrangement being such that the switch will open, on movement of said handle by the bar 29, simultaneously with the belt-shifting operation, and therefore the carding engine itself will come to rest.

.Where the carding engine is one of a series, the electrical connections maybe such, that if the sliver being fed to the first or any one of the series breaks, the opening of the normallyclosed limit switch 50;.onthat particular card-:

oted housing in tilted ing engine will interrupt the drive to all the carding engines in the series.

Also, in addition to the stop motion mechanism above described, the carding engine may be fitted with the known electrical device which on breakage of a sliver being fed, operates an electrical circuit to ring a bell, or to operate any other audible or visual means, to attract the attention of the operative.

Further, it is to be understood that other belt shifting or knock-off mechanism of different construction from that described, whether mechanical or electrical, may be used in combination with the described means for interrupting the drive to the feed rollers.

Referring now to Fig. 5 of the drawings, the mechanism according to the invention is shown applied to an Apperley Feed system, and the feed carriage and associated parts may be identical with that described with reference to Figs. 1 to 4, the feed carriage in this case being supported on guides 5|, 52 which are diagonally disposed relative to the side frames 53, 53 and the sliver is laid on a series of horizontal feed lattices 54 which feed the sliver to the licker-in 55 of the carding engine.
